Modes & levels (how Z2 works)
Stimulation (Massage): a fast, gentle pattern to trigger let-down. Start here at a comfortable level.
Expression: slower, deeper pulls to efficiently remove milk—adjust suction in small steps until milk moves well.
2-Phase / Alternating: Z2’s exclusive pattern that alternates sides for comfort and efficiency during longer sessions.
Comfort first: Use the lowest effective level that maintains flow; stronger suction is not always better.
Setup & session tips (step-by-step)
- Assemble & seat parts: Fit valves, membranes, and backflow protectors snugly to preserve the closed system.
- Align fit: Center your nipple in the flange. If you feel pinching or see blanching, adjust size (see below).
- Begin in Stimulation: Start at a gentle level to trigger let-down; switch to Expression once flowing.
- Fine-tune: Raise suction gradually; aim for steady flow with comfort. Try the alternating pattern if you prefer softer pacing.
- Hands-on pumping: Light breast compressions can help output. Stay relaxed and hydrated.
- Typical duration: Double sessions ~15–20 minutes; stop when comfortably empty.
- Between sessions (comfort): Some parents use silver nursing cups between feeds—remove before nursing or pumping.
Flange sizing (mm): fit = output
Measure nipple diameter in millimeters (exclude areola) and choose the closest flange size. Good fit reduces friction and can improve output. If in doubt, try one size up/down or consult an IBCLC for personalized sizing.
Cleaning & safe milk storage
- Parts care: Wash milk-contact parts with hot, soapy water after each use; rinse well and air-dry on a clean rack. Sanitize per brand instructions.
- Milk storage quick guide: Room ≤77°F (25°C): up to 4 hours · Refrigerator: up to 4 days · Freezer: ~6 months best (≤12 months acceptable). If thawed in the fridge: use within 24 hours; never refreeze; avoid microwaving.
FAQ
Is Z2 really “hospital-grade”?
“Hospital-grade” is not an FDA-defined term. Compare measurable specs instead: closed system, maximum suction (mmHg), noise (dB), portability, and controls.
How loud is the Z2?
It’s designed for quiet use around ~40 dB (a soft hum), helpful for night sessions and shared spaces.
How long does the battery last?
Usage-dependent, but many users see roughly 120 minutes total run time between charges.
Does it have auto-off and a night-light?
Yes—Z2 includes a backlit LCD, a night-light, and an auto-off around 30 minutes.
